UNITED STATES PATENT OFFICE.

SHELL-EXTRACTOR.

Application led. January 8, 1907.

To all whom it may concern:

Be it known that I, DANTE E. DONATI, a citizen of the United States,residing at Cayucos, in the county of San Luis Obispo, State ofCalifornia, have invented certain new and useful Improvements inShell-Extractors; and I do hereby declare the following to be a full,clear, and exact deseri tion of the invention, such as will enab eOthers skilled in the art to which it appertains to make and use thesame.

This invention relates to shell extractors and more articularly to thatclass which are designed for actuation by the shell ejecting mechanismofthe gun or rifle and the device is designed for use in extractingshells that have had their heads blown off or have become split due torepeated re-loading andrefiring.

Vhile numerous tools have been designed for this purpose, they haveproven generally unsatisfactory for the reason that they areunnecessarily complicated. The device embodied in my invention comprisesbut two members, a mandrel member and an expansible sleeve member',which is permanently engaged upon the mandrel member.

In the accompanying drawings, Figure 1 is a side elevation of anextractor constructed in accordance with my invention. Fig. 2 is asimilar view showing the extractor after having been driven to itsinitial position in the shell. Fig. 3 is a view similar to Fig. 2 butillustrating the position of the mandrel and sleeve member' of theextractor' when the same is being withdrawn from the ygun or rifle.

Referring mor'e specifically to the drawings, the extractor is shown ascomprising a mandrel member 5 and a sleeve member' The mandrel member isin the form of a stem which is provided at one of its ends with a head 7of substantially the same diameter as the head of the shell used in thegun or rifle and this head may either be formed integral With the stemor, as shown in the drawings, it may have a screw threaded connectionSpecification of Letters Patent.

therewith, this latter' form being preferable for the reason that whenso constructed, the sleeve 6 may be removed when desired. At its .endopposite its head end the stem comprising the mandrel is flared as at S,to such a degree that it will have substantially the same diameter asthe muzzle of the shell. The sleeve 6 is of slightly less length thanthe stem comprising the mandrel and normally has a slight play upon thestem. The sleeve however' is slit in opposite sides as at 9, at that endadjacent the flar'ed end of the stem, it being understood of course thatby thus slitting the sleeve, it may be expanded by the flared portion ofthe stem.

In using my extractor, the same is introduced into the decapitated shelland forced thereinto, the sleeve being of such diameter', before beingexpanded, that it will fit snugly within the muzzle of the shell. Theextractor' lever of the gun or rifle is then worked as in extracting theautomatic shell and it will be understood that the mandrel, being'withdrawn, will expand the sleeve and cause the same to grip the shellwith sufficient friotional force to permit of its extraction by anejecting mechanism of the gun.

II/vhat is claimed is:

A shell extractor comprising a mandrel for'med at one end with a headand flared at the other end, and a sleeve Vfitted snugly upon the shankof the mandrel, the sleeve being of but slightly less length than thedistance between the head of the mandrel and the minor end of its lower'ortion and being formed in Opposite sides with slits which are ofslightly greater length than the Vflared portion, the said flaredportion being designed to expand the slit portion of the sleeve withinthe muzzle of a shell.

In testimony whereof, I affix my signature, in presence of twowitnesses.
